👉 A fluorin is a type of protein that has been linked to the process of light-induced protein aggregation. Fluorins are found in many types of cells, including neurons and epithelial cells, where they serve as sensors or messengers for signaling. They can also be found in proteins that have undergone changes in their structure due to exposure to light, such as those involved in photosynthesis or the synthesis of neurotransmitters. The term "fluorins" is derived from the chemical symbol, "
